Joan Manuel Serrat (Barcelona, 1943) is a Spanish singer who writes his own songs, one of the figures most distinguished from the modern song so much in Castilian as Catalan language. Some of his topics of more success have been music poems based on the works of some of the most distinguished poets of both languages (as Antonio Machado and Miguel Hernández …), though some of his own letters might be considered between the most select of the poetry of both literatures.
